The Regulator 5mm Three-Finger Mittens use articulated panels to conform to the hand, splitting off the thumb and index finger so paddling and grip stay functional in water as cold as 45 degrees. The 85% Yulex natural rubber comes from Forest Stewardship Council-certified sources, and NetPlus recycled nylon lining adds a soft interior layer without depending on virgin synthetic material. What Our Gearhead(R) Experts Are Saying:"I can still find the rail of my board and adjust my grip mid-paddle, something a full mitt never lets me do once my hands are numb from the cold."
